Contactor, size 14, 3-pole, AC-3 450kW, 400 / 380V (690V) auxiliary switch 33 (3NO+3NC) bridge rectifier built in with changeover contactor 3TC44 AC operation AC 220 to 240V 50/60Hz 3TF6 vacuum contactor for switching motors.The 3TF6 vacuum contactors impress with their maximum performance combined with a compact design and high contact reliability. They are also characterized by a particularly long switching life. They are therefore particularly suitable for frequent switching in inching mode. Pre-assembled auxiliary switches reduce the complexity of your setup. The devices are approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready.They are available in two sizes, in AC or DC operation and in a wide power range. In the main circuit, the devices can be connected via rails. There are a wide range of accessories for these contactors, such as surge limiters, auxiliary switches or terminal covers.
